Quick Image Viewer (qiv) is a very small and pretty fast GDK/Imlib
image viewer. Features include zoom, maxpect, scale down, fullscreen,
brightness/contrast/gamma correction, slideshow, pan with keyboard
and mouse, rotate left/right, flip, delete (move to .qiv-trash/),
jump to image x, jump forward/backward x images, filename filter, and
you can use qiv to set your X11-Desktop background.

This requires imlib2.
